Hi Timothy,
I haven't had the pleasure of running double troubles but I did still isolate my speakers from the stands with Isoacoustic Orea Indogo. If you have no kids/dogs/ghosts in your house, you can do with 3 per speaker, but for full stability 4 is advised. You could try the bronze ones, but my speakers sat just over the weight limit (35lbs) to try those. There was a good improvement in focus and fixed some bass resonance. Shop around and you can find them on sale from time to time from places like Parts Connexion.
